Hydro Crunch Coco Coir Blocks are composed of 3 different types of compressed coco coir. This high quality, low sodium growing medium is an alternative to sphagnum peat moss. When hydrated with water, the blocks rapidly expand which saves you time and effort. Hydro Crunch Coco Coir growing mediums can be exclusively used by themselves, blended together or mixed with our Hydro Crunch expanded clay pebbles, perlite or topsoil.
